SCA: security update for org.apache.spark:spark-network-common_2.12, org.apache.spark:spark-network-common_2.13 (GHSA-6p6v-m64v-jx8q)

high Tenable Cloud Security Plugin ID 435638

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - This issue affects Apache Spark versions before 3.4.4, 3.5.2 and 4.0.0. Apache Spark versions before
 4.0.0, 3.5.2 and 3.4.4 use an insecure default network encryption cipher for RPC communication between
 nodes. When spark.network.crypto.enabled is set to true (it is set to false by default), but
 spark.network.crypto.cipher is not explicitly configured, Spark defaults to AES in CTR mode
 (AES/CTR/NoPadding), which provides encryption without authentication. This vulnerability allows a man-in-
 the-middle attacker to modify encrypted RPC traffic undetected by flipping bits in ciphertext, potentially
 compromising heartbeat messages or application data and affecting the integrity of Spark workflows. To
 mitigate this issue, users should either configure spark.network.crypto.cipher to AES/GCM/NoPadding to
 enable authenticated encryption or enable SSL encryption by setting spark.ssl.enabled to true, which
 provides stronger transport security. (CVE-2025-55039)
